What will be 1.5.77, which should have no functional difference as
none of the relevant code has changed:
snowleopardserver:~ shadow$ kinit shadow
Please enter the password for shadow@ANDREW.CMU.EDU:
snowleopardserver:~ shadow$ aklog dementia.org
demsnowleopardserver:~ shadow$ cd /afs/dementia.org/usr/shadow
snowleopardserver:shadow shadow$ ls -l
[...]
snowleopardserver:shadow shadow$ cat > test4
hgkhasdfgkhdsfkhgdfh
snowleopardserver:shadow shadow$ cat test4
hgkhasdfgkhdsfkhgdfh
snowleopardserver:shadow shadow$ sudo fs discon offline
Password:
Discon mode is now "offline"
snowleopardserver:shadow shadow$ echo foo > test4
snowleopardserver:shadow shadow$ cat test4
foo
snowleopardserver:shadow shadow$ sudo fs discon online -uid 501
Discon mode is now "online"
snowleopardserver:shadow shadow$ cat test4
foo
snowleopardserver:shadow shadow$ fs flushv .
snowleopardserver:shadow shadow$ cat test4
foo
the "fs discon online -uid 501" is needed because OSX has no PAGs, so
the fs discon online won't have "my" tokens, since they're accessed by
uid.
I'll have to try on Linux, because that's the obvious difference. But
it works on OSX as it did before.
