Ehm, you might want to explain a "little" bit more.

[Comment 3 Francesco R. (RETIRED) 2006-05-06 10:47:04 UTC]

ok, the command in question sure is not "emerge" but "ebuild". 

fex:
ROOT="" ebuild mysql-5.1.7_beta.ebuild digest && rm -rf {tmp,var}

instead, upgrading to 2.1_pre10-r3 fixed the problem regarding the "infinite loop", it was a "stat()" on a non existant directory reiterated with a "/" added every time the stat was issued.

So the biggest problem is fixed however what about to filter stupid values of ROOT var?

Sure, I'll fix that.  I was able to reproduce with `ROOT="" emerge moo`.

[Comment 5 Zac Medico 2006-05-06 11:38:11 UTC]

Fixed in svn r3326.

[Comment 6 Zac Medico 2006-05-07 23:09:41 UTC]

This has been release in 2.1_pre10-r4.
