Hi all, here's an idea to enhance file systems's usefulness: virtual partitioning. Let's say I have a FreeBSD system on one big partition. Virtual partititioning would allow me for example to 'reserve' space for specified directories (at mount time let's say). Examples: 1- / is 1GB, I reserve 250 MB for /var/log. It means / will get full at 750MB. 2- / is 2GB, I reserve 750 MB for / not including /var/log. It means, /var/log can never fill / up. / gets full at 750MB and /var/log gets full at 1250MB. 3- / is 2GB, I reserve 750 MB for / not including /var/log. I reserve 250MB for /var/log. The rest is free unallocated space I may choose to reserve/allocate later, like spare space. Ideally, the reservations could be made/altered on a mounted file system, possibly using a remount with options. I'm not the one who's going to implement that, I am just providing the idea. Regards, Yves Lepage
