Install commands should not be used to specify soft dependencies among
modules. When loading modules it's much better to have a softdep that
modprobe knows what's being done than having to fork/exec another
instance of modprobe to load the other module.
By using a softdep user has also an option to remove the dependencies
when removing the module (and if its refcount dropped to 0)

In this case, the following can be added to config files in
/etc/modprobe.d/ as:
-install bonding /sbin/modprobe tg3; /sbin/modprobe e1000;
- /sbin/modprobe --ignore-install bonding
+softdep bonding pre: tg3 e1000
This will load tg3 and e1000 modules before loading the bonding one.
Full documentation on this can be found in the modprobe.d and modprobe
the sound card. Installation dependencies must be written in configuration
files under /etc/modprobe.d/ directory:
-install ad1848 /sbin/modprobe aedsp16 && /sbin/modprobe -i ad1848
-install opl3 /sbin/modprobe aedsp16 && /sbin/modprobe -i opl3
+softdep ad1848 pre: aedsp16
+softdep opl3 pre: aedsp16
Then you must load the sound modules stack in this order:
sound -> aedsp16 -> [ ad1848, opl3 ]
Alternatively, if you have compiled in kernel level ISAPnP support:
alias char-major-14 sb
-post-install sb /sbin/modprobe "-k" "adlib_card"
+softdep sb post: adlib_card
options adlib_card io=0x388
The effect of this is that the sound driver and all necessary bits and
