Hi,
new version with new features (and BUGs ;p)
Added check if ntfsfix from sysutils/ntfsprogs is available, if Yes then
try to fix the NTFS filesystem before mouting it.
Added GPL3 License ... just joking ;) ... added FreeBSD License to the file.
Added 'noatime' as a default mount option when possible.
Added TIMEOUT so when an 'orphan' STATE file lock remains, it will be deleted after a TIMEOUT.
Added /usr/local/etc/devd/automount.devd file instead of messing with the base system config at /etc/devd.conf.
Added config file to be used from /usr/local/etc/automount.conf file, possible options are (these are defaults):
MNTPREFIX="/media"
LOG="/var/log/automount.log"
STATE="/var/run/automount.state"
ENCODING="en_US.ISO8859-1"
CODEPAGE="cp437"
DATEFMT="%Y-%m-%d %H:%M:%S"
USERUMOUNT="NO"
Mine config currently has only these:
ENCODING="pl_PL.ISO8859-2"
CODEPAGE="cp852"
USERUMOUNT="YES"
The USERMOUNT otions if set to YES (default to NO) will 'chmod +s /sbin/umount',
so You can click the ^ button on the devices list in NAUTILUS.
These newly mounted devices appear on NAUTILUS sidebar (only with /media prefix).
But THUNAR and PCMANFM does not do that, You know any other FMs that display mounted thumb drives/devices?
EXAMPLE: http://i.imgur.com/qdKdl.png
First BUG: (not fixed yet, but workaround already is working)
TEST/BUG/CASE:
Plug in FAT32 and NTFS drives at the same time, when FAT32 device will be detected first, it will get mounted and the NTFS drive will be mounted TWICE, so I added __check_already_mounted function to check if it is not already mounted.
Below are current script and config files.
