I had just been wondering how to set up /dev/disk/by-id; I have a helper for mdev that will set up /dev/disk/by-uuid/ and /dev/disk/by-label/ symlinks (by parsing the output of 'blkid'): https://github.com/idunham/mdev/blob/master/helpers/disk_link.sh It's released into the public domain via the unlicense. <snip> > === TODO === > There's still a few major shortcomings before I'm comfortable tagging an > alpha release, which I list below: > * vdevd needs an accompanying init script to mount devtmpfs and set up: > -- /dev/stdout > -- /dev/stderr > -- /dev/stdin > -- /dev/core > -- /dev/shm > -- /dev/MAKEDEV > -- /dev/fd > -- /dev/log > -- /dev/xconsole > -- and probably others ln -s /proc/kcore /dev/core ln -s /proc/self/fd /dev/fd ln -s /proc/self/fd/0 /dev/stdin ln -s /proc/self/fd/1 /dev/stdout ln -s /proc/self/fd/2 /dev/stderr # MAKEDEV is part of package makedevs; # it should be copied to /dev if it exists [ -x /sbin/MAKEDEV ] && cp /sbin/MAKEDEV /dev/MAKEDEV || \ ln -s /bin/true /dev/MAKEDEV /dev/log is the responsibity of the syslog implementation, which is not started by the device manager. /dev/xconsole is not something I have on my main (udev-based) partition - I think it's the result of running xconsole? /dev/shm is either a mountpoint for a tmpfs filesystem or a link to one. An old FHS-style system will do: mkdir /dev/shm && mount -t tmpfs shm /dev/shm On systemd-influenced systems, it's instead roughly: # in mountdevsubfs.sh, from initscripts mount -t tmpfs tmpfs /run mkdir -p /run/lock /run/shm mount -t tmpfs tmpfs /run/lock mount -t tmpfs tmpfs /run/shm #in udev, which runs before mountdevsubfs.sh mountpoint -q /dev/shm/ && umount /dev/shm/ mountpoint -q /dev/pts/ && umount /dev/pts/ #(re)mount /dev and populate it mkdir -p /dev/pts && mount -t devpts devpts /dev/pts #I'm not sure where this is. ln -s /run/shm /dev/shm HTH, Isaac Dunham _______________________________________________ Dng mailing list Dng@lists.dyne.org https://mailinglists.dyne.org/cgi-bin/mailman/listinfo/dng
