ok, that helped a little, but is there a way to mount a mfs partition on a system with no hard drive? i'm making a freebsd OS that boots from a cdrom, and needs to mount /var and /tmp as mfs so that they can be writeable. any ideas how to do this without a hard drive, which would also mean doing it without a swap partition nathan On Saturday 19 January 2002 07:46 am, you wrote: > On Sat, 19 Jan 2002, Nathan Mace wrote: > > every example i can find conserning mfs filesystems, mounts the mfs > > "partition" from the swap partition. is there a way to mount it from a > > section of RAM instead of a section of swap? > > > > please send me a copy of any replies, i am not a member of this mailing > > list. thanks > > > > nathan > > > > To Unsubscribe: send mail to majordomo@FreeBSD.org > > with "unsubscribe freebsd-questions" in the body of the message > > the mfs is used to see a section of ram as a filesystem. the advice i got > from more experience people is that 'if u got a lot of ram, put the /tmp > as mfs'. > > which is what i did... > > i'm sending you the output of the /etc/fstab of my sys: > > # Device Mountpoint FStype Options Dump > Pass# > /dev/ad0s1b none swap sw 0 0 > /dev/ad0s1a / ufs rw 1 1 > /dev/ad0s1g /home ufs rw 2 2 > /dev/ad0s1e /usr ufs rw 2 2 > /dev/ad0s1f /var ufs rw 2 2 > /dev/acd0c /cdrom cd9660 ro,noauto 0 0 > /dev/ad0s1a /tmp mfs rw 0 0 > proc /proc procfs rw 0 0 > > > see, /tmp is mount as mfs. also note that the mountpoint is effectively > '/' (root). both the '/' ( second line) and the '/tmp' mount on the > ad0s1a. > > the output of df command is: > Filesystem 1K-blocks Used Avail Capacity Mounted on > /dev/ad0s1a 63503 51220 7203 88% / > /dev/ad0s1g 13174185 1836360 10283891 15% /home > /dev/ad0s1e 2977230 1881320 798187 70% /usr > /dev/ad0s1f 347295 16125 303387 5% /var > mfs:22 63471 3 58391 0% /tmp > procfs 4 4 0 100% /proc > > showing 64M ram mounted on /tmp as mfs... > > hope this helps... > > Regards > > --Bernie To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
