#2843: Make ld.so.conf include files from /etc/ld.so.conf.d
-------------------------+--------------------------------------------------
Reporter: synthehol | Owner: lfs-book@…
Type: enhancement | Status: new
Priority: normal | Milestone: 6.9
Component: Book | Version: SVN
Severity: normal | Keywords: glibc dynamic loader ld.so.conf
-------------------------+--------------------------------------------------
Currently, LFS lists directories containing libraries directly in
/etc/ld.so.conf. However, there are advantages in changing the contents of
ld.so.conf to "include /etc/ld.so.conf.d/*.conf", and then place it's
current contents in /etc/ld.so.conf.d/glibc.conf.
Personally, I have been using this method for years (and so have the big
distributions) and found it to be the more elegant solution.
Advantages become apparent when you use BLFS and/or often (un)install
software in /opt:
Each new package requiring additional search paths can store them in their
own file, meaning ld.so.conf does not have to be modified any more; No
chance of accidentally removing existing paths or cluttering up the file.
When uninstalling a package, in stead of modifying ld.so.conf again, you
can simply delete the configuration file belonging to that package.
Concerns:
Both LFS and BLFS should be modified. Only modifying LFS defeats the
purpose of the change.
Should BLFS be modified accordingly, people who blindly copy-paste
commands and have an older version of LFS installed (and therefore do not
have ld.so.conf.d) will experience problems. To limit this as much as
possible, BLFS should (at least temporarily) warn "Make sure you have set
up /etc/ld.so.conf.d as explained in LFS-6.9 and if not, make this change
now.".
