yum update of glibc needs space that's already there

[Thiers Botelho]

Hi all,

When doing 'yum update' for a couple of glibc packages, it complained 
requiring 41MB on '/' filesystem:

==========================================================================
[root at inf-cpg-c2036-lx root]# yum update gl*
Gathering header information file(s) from server(s)
Server: Fedora Core 1 - i386 - Base
Server: Fedora Core 1 - i386 - Released Updates

I will do the following:
[update: glibc 2.3.2-101.4.i686]
[update: glibc-common 2.3.2-101.4.i386]
Is this ok [y/N]: y

BUT at the time I had 151Mb available on same '/' filesystem:

==========================================================================
[root at inf-cpg-c2036-lx root]# df -m

BTW, my versions of updating apps are (from /var/log/yum.log ):

And on a side note, I have exactly the same problem with 'yum update moz*' 
- the requirement for mozilla and friends is actually bigger. But I'd like 
to solve glibc first.

OK. So 1 have 4 questions:

1. Who among yum / rpm / glibc is actually requesting space ?

2. Is this some kind of bug? Or should I understand that what's actually 
needed is a total of (151 + 41 = 192) Mb ?

3. Can I find out on which dir(s) this space will be used ? (and probably 
rearrange my cramped system with specific filesystems for those)

4. Is there a doc / page / ebook somewhere where I could understand this 
stuff better ?


Thnx all

Thiers
