# Handle /etc/fstab entries and /mnt directories for removable devices
# so they are mounted under /mnt directory.
# This script is called by /etc/udev/rules.d/10-porteus-fstab-update.rules

# Inspired by 'udev-fstab-update' from Slax 6.1.2 but rewritten from scratch
# for Porteus by fanthom <fanthom@porteus.org> and Ahau <ahau@porteus.org>

# Variables initialized by the udev environment:
# $ACTION (add, change, remove)
# $DEVNAME (device name including path)
# $ID_FS_TYPE (filesystem type)

# Exit if called during boot:
#ps a | grep -q 'bash /etc/rc.d/rc.S' && exit

# Exit if 'nohd' cheatcode is used:
egrep -qo " nohd( |\$)" /etc/bootcmd.cfg && exit

# Our variables:
FSTAB=/etc/fstab

# Make sure the part of a script after 'mutex_lock' call is atomic,

# The lock directory is saved in /dev instead of /tmp, because /tmp may be
# readonly at the time when the lock is needed (eg. when udev is starting)
