- Having written a Xenix filesystem for Linux (more on why later :-),
- I figure I might as well see if anyone else wants it.
-
- Why? I have gobs of source and data files and don't want two copies of it all
- (one for when I boot Xenix and one for when I boot Linux). Now I can boot
- either and have access to *one* copy. Of course, I still need separate
- binaries, .o's, etc. but no big deal. I also have one news spool directory
- and can read news in Xenix or Linux (and mail and uucp logs, etc.).
-
- I also wrote it because I have the CMS Xenix device driver for the Jumbo 250
- tape drive. I back up Linux when I back up Xenix! Way cool!
-
- My setup is now:
-
- 200MB IDE 30MB DOS
- 50MB Xenix (root+swap)
- 60MB Linux (root+swap)
- 60MB Xenix/Linux (/usr/spool)
-
- 1Gig SCSI 100MB DOS
- 300MB Xenix/Linux (/home)
- 300MB Xenix/Linux (/usr/src)
- 360MB Xenix/Linux (/u)
-
- For Linux'ers wanting a *real* filesystem :-) this ain't it. File names are
- still max 14 chars and in this case there are no symbolic links.
-
- You also *need* Xenix. I haven't written mkfs/fsck for Linux, but plan
- to "sometime". The filesystem was quite easy given that the Minix filesystem
- isn't *that* different (they're all SysV variants). The only real difference
- (that comes to mind) is the bitmaps vs free list, so I should be able to take
- Linux's mkfs/fsck and adapt them.
-
- I don't have Xenix divvy table or badtrk table support, and don't plan to for
- the nonce. I just don't need them, and plugging these in seemed to require more
- substantial changes to Linux than just plugging in a filesystem.
- For my Xenix/Linux filesystems, I just did an mkfs on the entire partition,
- and bypassed divvy.
-
- So, any takers? (If so, please email).
