Oh. I assume 1.7.0 is the one currently in CVS. That would explain why
I can't find the logic to write the mount registry keys in the CVS
sources. It's not there. Well, that's one less thing I have to think
about. Would you mind pointing me to where I should have found that?
Reading the ChangeLog in "src/winsup/cygwin" I can see a great many
changes from the process of moving over to the new fstab system, but I
assume there was an announcement of the change somewhere other than
cygwin-developers.
As for why I care, I'm looking through the CVS sources to see what
needs to be done to make a portable (run from USB key or similar)
version of Cygwin, and to familiarize myself with the inner workings
of Cygwin in general. The changes that I think are needed to make
Cygwin portable (that I've come up with so far; this is far from
comprehensive):
- Dynamic Calculation of Mountpoints
* This seems to be done already in CVS, although to what extent I don't know
- Single User System
* Stop using the username and domain from Windows.
* Instead, use a single user/group, like "cygwin:cygwin"
* Use a single homedir regardless of windows user, probably just "/home"
* I did this by messing with /etc/profile, but it would be better
to change Cygwin itself to not care.
- Special Mountpoint for Root of Portable Drive (Optional)
* Mount the USB key on something like "/portdrive" or "/cygdrive/portable"
* This makes it so you can get to other things on the USB key
without knowing the drive letter
* For example, I would like to symlink "/home/devel" to
"/cygdrive/portable/Devel/"
I was trying to work on the first one, but it seems that's been fixed
in CVS already.
