# Hacks for Slackware ARM.

# e2fsprog-1.41.x enforces a check and breaks, so we can configure e2fsprogs
# if we find ourselves on this platform (when the package is installed)
# to ignore this problem.
# Create the config file:
cat << EOF > etc/e2fsck.conf.new
# Automatically added during the installation of the e2fsprogs package
# because we detected you were installing on an ARM-Versatile platform.
# These options stop e2fsck from erroring/requiring manual intervention
# when it encounters bad time stamps on filesystems -- which happens on
# the Versatile platform because QEMU does not have RTC (real time clock)
# support.
# Other devices such as the Seagate Dockstar also don't have an RTC so you'll
# want to do this for those too.  Unfortunately I don't know of a way to check
# for whether we're running on such a device so I can't automate it.
