- Okay, question for the gurus.
-
- I stopped testing Interactive Unix (Sun v3.0, SYSV/386v3.2) because,
- frankly, Linux 0.96c seems more stable and more usable (not to mention
- *free* with sources available ;-> ) and wiped the Interactive partition
- off my drive.
-
- I have a 202mb drive. My partitions are:
- /dev/hda1 MS-DOG 32+mb
- /dev/hda2 minix 30mb /
- /dev/hda3 minixsw 20mb (swap)
-
- ...and now for the fun stuff...
-
- I used efdisk to make primary partition 4 an extended partition (the
- type is 5, Extended DOS partition, I believe) encompassing the 120mb
- remaining. I then proceed to hit 'n' (new partition) and it doesn't
- prompt me for partition # any more; I proceed to finish my partition
- table as follows:
-
- /dev/hda4 extdos 120mb
- /dev/hda5 minix 64mb /usr
- /dev/hda6 minix 46mb /home
- /dev/hda7 minix 10mb /misc
-
- I originally installed Linux (using the script - greast job!) only on
- /dev/hda{2,3} using a mkfs on hda2 and a mkswp on hda3. Got everything
- working, and decided to take the chance; I mkfs'ed hda{5..7}, and
- mounted them. df reports the space there, I can copy files onto them,
- create directories, umount and mount them in other places, etc.
-
- Here's my question(s):
-
- 1) Is this supposed to work? If not, will I suffer any
- inconceivable consequences down the road?
- 2) Is the extended file system *just* to get partitions
- >64mb and longer filenames, or also for >4 partitions?
-
- Here's my basis of understanding on Linux's file system right now:
-
- a) Only 4 partitions can be used (excepting the extended
- filesystem, which I have heard needs a 'mkefs' command
- to create, and may require recompiling with a different
- library function to make shells and other programs "see"
- the directories and files within them)
- b) Linux 0.97 should support longer filenames and much
- larger partitions (on the order of terrabytes?)
-
- Fantastic system, BTW. Everyone who work{s|ed} on this deserves a six-pack
- from everyone who uses it (of course, we'll never get updates and ports if
- the entire development team is swimming ;-> )
-
- Oh. Eventually I may look into writing a driver for my Colorado Jumbo 250
- tape backup (unless someone is already endeavoring - let me know) -- if
- anyone would like to keep me from this certain misery, an Exabyte would go
- a long way!
- Thanx,
