# Here's the situation. Because of the practice of keeping the local
# time (rather than UTC) in the system's clock, at any given time half
# of the people doing an install will be creating files that upon
# reboot will appear to have been created in the future.
#
# There are a lot of things that aren't happy when that happens. The
# one that screams the most loudly is e2fsck, and we don't want to
# anger that! Sometimes it even proceeds to check the partitions just
# to be sure the user is fully punished.
#
# But, there's a simple solution. If we set the (temporary) Linux clock
# to yesterday (-24h), then there's no way that could occur. Everything
# on the system will be in the past (but not too far in the past).
# Since files will quickly be put into use and given the correct after
# reboot, this really shouldn't have a negative impact. Plus, it affects
# only newly created files during installation -- any file shipped in a
# package will have an accurate time of creation. (for its timezone ;-)
#
# Update: We have to use 2 days ago, or chroot()+timezone offset might
# still be in the future... <sigh>

If you're upgrading an existing Slackware system, you might want to
remove old packages before you run 'setup' to install the new ones. If
you don't, your system will still work but there might be some old files
left laying around on your drive.

Just mount your Linux partitions under /mnt and type 'pkgtool'. If you
don't know how to mount your partitions, type 'pkgtool' and it will tell
you how it's done.

To partition your hard drive(s), use 'cfdisk' or 'fdisk'.
To start the main installation (after partitioning), type 'setup'.
