Unable to specify log location outside of %unixroot

[Lewis Rosenthal]

On this machine, %unixroot is J:

Changing log location in yum.conf to systemwide log dir (c:/var/log) produces output from yum such as:

[j:\devel\yumie\yumie_preview7\scripts]yum info clamav

I have not tried relocating the yum cache, but suspect similar difficulty.

[Lewis Rosenthal]

Confirmed: yum cache path is also hardcoded to look at /@unixroot/<blah>. Thus, specifying cachedir=/@unixroot/somewhere-else yields an error that /@unixroot/@unixroot/somewhere-else cannot be found.

Related to issue #95.

maybe you can try using

/@system_drive/var/log

instead, this does not expose a drive letter...

[Lewis Rosenthal]

Unfortunately, Yuri, that gets me a nice, new directory in %unixroot%:

 1-13-15  11:27         <DIR>      124  @system_drive

Entry in yum.conf says:

logfile=/@system_drive/var/log/yum.log

Looks like without some way of faking a mount under %unixroot%.

Path rewriter says:

/var/log = %LOGFILES%

Environment says:

LOGFILES=C:\var\log

Changing logfile directive to:

logfile=/var/log/yum.log

seems to ignore the path rewriter (as expected, I suppose).

Looks like we'll need to wait for a fix on this until the drive letter support is working. Thanks for the suggested workaround, though. It was worth trying.

[Yuri Dario]

Moving unixroot tree away from the root directory, while seems to be working, is not tested and we don't have the (human) resources to test all possible situations.
