ΤΟ ΠΑΡΟΝ ΑΡΘΡΟ ΕΙΝΑΙ ΠΙΑ OUT OF DATE
Το Slackware δεν είναι μονο η αρχαιότερη διανομή Linux αλλά εξακολουθεί να παραμένει πιστό στην UNIX φιλοσοφία, KISS...
Δηλαδή σε απλά Ελληνικά, κράτα το σύστημα σου όσο πιο απλό μπορείς, σχεδόν ηλίθια απλό...
Επίσημα το Slackware υποστιρίζει σε DE, το KDE (full plasma) και το XFCE. Επίσης κατά την εγκατάσταση (full) υπάρχουν και 3-4 WM...
Με το systemd δεν έχει προς το παρόν ακόμα παρτίδες, και η επίσημη θέση του αφεντικού και των developers είναι πως όσο δεν το έχουμε ανάγκη δεν υπάρχει λόγος να το εγκαταστήσουμε στην διανομή...
Αυτό ερμηνεύεται με πολλούς τρόπους βέβαια, πάντως για την ώρα δεν υπάρχει τέτοια πιθανότητα στο ορίζοντα αφού το 90% των χρηστών της διανομής δεν επιθυμούν κάτι τέτοιο.
Οι επικριτές του Slackware συνήθως εστιάζουν στην "αρχαία δομή και αρχιτεκτονική" Slackware , όπως και στο ότι δεν είναι μια "μοντέρνα" διανομή κ.α
Αυτά είναι γούστα βέβαια και φυσικά καμία διανομή δεν είναι θρησκεία ή δόγμα...
Προσωπικά δεν είμαι οπαδός κανενώς απλά κάνω το κέφι μου όπως θέλω και το Slack με φτιάχνει...
Σας παρουσιάζω λοιπόν μια προσωπική μου δουλειά, για την φάση και την εμπειρία.
Ίσως κάποιος νέος να έρθει σε επαφή για πρώτη φορά με το Slackware μέσω του Slackware-live.iso που έφτιαξα ή κάποιος παλιός να ξαναβρεί την πρώτη του αγάπη

To iso αυτό είναι ανεπίσημο βέβαια και δεν χρειάζεται να τα λέμε , αλλά επειδή χρειάζεται...
ΤΟ ΧΡΗΣΙΜΟΠΟΙΕΊΤΑΙ ΜΕ ΔΙΚΗ ΣΑΣ ΕΥΘΗΝΗ. ΔΕΝ ΥΠΑΡΧΕΙ ΚΑΠΟΙΟΣ ΕΙΔΟΥΣ ΕΓΓΥΗΣΗ ΓΙΑ ΑΥΤΟ ΤΟ ΠΡΟΙΟΝ
ΤΟ ΟΠΟΙΟ ΜΠΟΡΕΙ ΝΑ ΠΡΟΚΑΛΕΣΕΙ ΖΗΜΙΑ ΣΤΟΝ ΥΠΟΛΟΓΙΣΤΗ ΣΑΣ ΚΑΙ ΔΕΝ ΣΑΣ ΣΥΝΙΣΤΩ ΝΑ ΤΟ ΧΡΗΣΙΜΟΙΕΙΣΕΤΑΙ ΓΙΑ ΕΠΑΓΓΕΛΜΑΤΙΚΗ ΧΡΗΣΗ ΑΛΛΑ ΜΟΝΟ ΓΙΑ ΕΚΠΑΙΔΕΥΤΙΚΟΥΣ ΣΚΟΠΟΥΣ.
Επειδη λοιπόν το Slackware είναι απαρχαιωμενη διανομή , χωρίς systemd και καθόλου μοντέρνα,
εδώ υπάρχει ένα
live_slackware iso και εδώ το
md5 έχει ένα ωραιώτατο μοντέρνο GNOME 42.3 το οποίο χτίστηκε λιθαράκι λιθαράκι για ένα Slackware64-current σύστημα χωρίς systemd
και έχει έτοιμο τον χρήστη
live με κωδικό
liveκαι το
root με κωδικό
rootΜπορείτε να το γράψετε σε στικάκι από 3.5 G και πάνω είτε με dd
dd if=slackware64-live-current.iso of=/dev/sdX status=progress
είτε με τον "Slackware" τρόπο, για 100% εγγυημένο απότέλσμα.
Δηλαδή πάρτε το συμηνένο script και ρίξτε το στον ίδιο καταλογο με το iso.
Έπειτα ανοίγουμε ένα terminal στον καταλογο και εκτελούμε
sh iso2usb.sh -i slackware-live-current.iso -o /dev/sdX
Είτε με dd είτε με το script το γράψετε, προσοχή στο /dev/sd
X ... όπου
Χ βάλτε το γράμμα που αντοιστιχεί στο usb stick σας. Πιθανά να είναι /dev/sd
b , μη σβήσετε κανένα εξωτερικό σκληρό και μετα με βρίζετε...

ενα πρόχειρο βιντεάκι με boot σε Vbox... για να δω αν παίξει οκ wayland + pipewire

αφού αυτό θέλουν τα μοντέρνα ντέσκτοπ...

# Purpose: to transfer the content of Slackware's Live ISO image

# WARNING: Your USB thumb drive may contain data!
# If you are not using the refresh option '-r' then this data will be *erased* !
#
# $(basename $0) accepts the following parameters:
# -c|--crypt size|perc Add LUKS encrypted /home ; parameter is the
# requested size of the container in kB, MB, GB,
# or as a percentage of free space
# (integer numbers only).
# Examples: '-c 125M', '-c 2G', '-c 20%'.
# -d|--devices List removable devices on this computer.
# -f|--force Ignore most warnings (except the back-out).
# -h|--help This help.
# -i|--infile <filename> Full path to the ISO image file.
# -l|--lukshome <name> Custom path to the containerfile for your LUKS
# encrypted /home ($SLHOME by default).
# -o|--outdev <filename> The device name of your USB drive.
# -p|--persistence <name> Custom path to the 'persistence' directory
# or containerfile ($PERSISTENCE by default).
# -r|--refresh Refresh the USB stick with the ISO content.
# No formatting, do not touch user content.
# -s|--scan Scan for insertion of new USB device instead of
# providing a devicename (using option '-o').
# -u|--unattended Do not ask any questions.
# -v|--verbose Show verbose messages.
# -w|--wait <number> Add <number> seconds wait time to initialize USB.
# -y|--layout <x,x,x,x> Specify partition layout and sizes (in MB).
# Default values: '$DEF_LAYOUT' for 3 partitions,
# the '-1' value for partition 3 meaning
# 'use all remaining space',
# and an empty 4th value means 'do not reserve
# free space for a custom 4th partition'.
# -C|--cryptpersistfile size|perc
# Use a LUKS-encrypted 'persistence' file instead
# of a directory (for use on FAT filesystem)
# Format for size/percentage is the same
# as for the '-c' parameter.
# -P|--persistfile Use a 'persistence' container file instead of
# a directory (for use on FAT filesystem).
