<DIV><FONT face=Arial size=2><SPAN class=413183912-06012009>I have been working
on the development of a product using uClinux as one of its embedded operation
systems. The development has been on PC's running Fedora 8 and 9. My
work is requiring me to understand Linux in more detail than before. I
have several petty questions that I would like to bug you
with.</SPAN></FONT></DIV>

<DIV><FONT face=Arial size=2><SPAN class=413183912-06012009>1. On one of
my PC's I upgraded from Fedora 6 to 9 in one step. I mostly went o.k. I
find that in my /usr/src/kernels directory four subdirectories with kernel
source. Two for fc6 and two for fc9. Why are there two src
directories for each version?</SPAN></FONT></DIV>

<DIV><FONT face=Arial size=2><SPAN class=413183912-06012009>2. I noticed
that the kernel that is running (uname -r) is not the highest numbered 9
kernel. In fact it is not any of the kernels in
/usr/src</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN class=413183912-06012009>
2.6.25-14.fc9.i686 is listed as running</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN class=413183912-06012009>
2.6.25-14.fc9.i586 is in src as well as 2.6.27.9-73.fc9.i586</SPAN></FONT></DIV>

<DIV><FONT face=Arial size=2><SPAN class=413183912-06012009>3. Under
/usr/src there is a redhat directory tree, but there are no files. What is
it?</SPAN></FONT></DIV>

<DIV><FONT face=Arial size=2><SPAN class=413183912-06012009>4. Kernel
numbering: When is a dash used in the version number?</SPAN></FONT></DIV>

<DIV><FONT face=Arial size=2><SPAN class=413183912-06012009>5. make xconfig will
not run as it is seems to be compiling for KDE (kconfig) while I am running
gnome. Is there a xconfig for gnome?</SPAN></FONT></DIV>

<DIV><FONT face=Arial size=2><SPAN class=413183912-06012009>6. When I was
running fc6, the auto updating feature would always report that the system was
up-to-date. I assumed that was because fc6 was too old. When I did
an update to fc9, I found that one of the fc6 kernel directories was
changed.</SPAN></FONT></DIV>

<DIV><FONT face=Arial size=2><SPAN class=413183912-06012009>7. Is this list of
question a sign that I should go with Red Hat
Enterprise?</SPAN></FONT></DIV></BODY></HTML>
