It would be 'less terrible' if a few 'classes' of mounts were created as part of the standard, with actual devices/filesystems below each, although the potential to overly clutter / still exists. Example: /audio /audio/ipod /audio/generic /video/ /video/sonycam /video/generic etc...actually, I think I'm still less than crazy about this one ;-) >- All mount points in /mnt (e.g. /mnt/cdrom, /mnt/camera, /mnt/windows/C) ><- breaks > FreeBSD standard for an empty /mnt > > Don't like it, as others have stated, too many of us are in the habit of having an 'empty' /mnt , unless we chose to create subdirectories, and I often mount something I know will be used short-term only at /mnt and use it as a single point, instant mount point for 'whatever' I'm mounting temporarily. >- Anyplace at all > > Nope. This just leads to obnoxious workarounds and/or additional configuration files for developing software that needs to use either. Again, using a 'device class heirarchy' comes to mind, like a 'whereis mountd', where a program could ask for the location of a specified class of device, and then in turn scan any mounted devices, but this one's a BIT out of scope of the FS project ;-) >- Anyplace but /mnt (i.e. what the FHS 2.2 currently specifies) > > K, but same as above, although I suppose it depends if they are looking to only define a single top level directory, or possibly more than one, eg subdirectory/mount points? >- Anyplace but / or /mnt (e.g. /vol/cdrom, /var/mnt/camera, >/media/windows/C) > > As long as it's consistent and not ALL of the above for the given devices ;-) Again, prefer a single dir entry into /, which can grow as need be... > (some suggestions have been /media, /mounts, /vol, /var/mnt, > and /var/tmp/removable.
