i made an update and got a fstab.pacnew file...
I'm using the latest Version downloadable on raspberrypi.org.
old (fstab):
$this->bbcode_second_pass_code('', '
#
# /etc/fstab: static file system information
#
# <file system> <dir> <type> <options> <dump> <pass>
devpts /dev/pts devpts defaults 0 0
shm /dev/shm tmpfs nodev,nosuid 0 0
/dev/mmcblk0p1 /boot vfat defaults 0 0
/dev/mmcblk0p3 none swap defaults 0 0
/dev/mmcblk0p4 /home ext4 defaults 0 2
')
new (fstab.pacnew)
$this->bbcode_second_pass_code('', '
#
# /etc/fstab: static file system information
#
# <file system> <dir> <type> <options> <dump> <pass>
')
i'm confused

devpts, shm and /dev/mmcblk0p1 are in fstab since installation.
/dev/mmcblk0p3 and /dev/mmcblk0p4 are additional patitions made by me.
how to merge these 2 files?
can somebody help me?
thx!
