[ptxdist] [PATCH v3] lvm2: move lvmdump and fsadm into separate options

[ptxdist] [PATCH v3] lvm2: move lvmdump and fsadm into separate options

[Sven Püschel]

Move lvmdump and the fsadm command into a separate option, as both
commands are bash scripts and therefore need bash as a dependency.
As these commands may not be used, we don't add bash as a dependency to
the much bigger LVM2_LVM_TOOLS option but instead add distinct options
for these commands.

v3
- added new options instead of adding bash to LVM2_LVM_TOOLS
- added RUNTIME flag to the bash dependency
v2
- added

I think you need to select LVM2_LVM_TOOLS here. The scripts probably don't
make sense without the actual binaries and the targetinstall stage will
fail as well.

No 'default y' I think. These are tools typically used during development.
And automatically enabling bash during an update is not so nice.

Same here.

These are guarded by the same `if·LVM2_LVM_TOOLS` that is also used for 
`LVM2_STARTSCRIPT`. The diff just hides this fact.

Therefore they cannot be selected if LVM2_LVM_TOOLS is disabled.

Btw. the makefile doesn't have the nested if, as it should be handled by 
the kconfig.

My reasoning here was potential backwards compability (e.g. when you had 
all tools installed previously you don't want to accidentially kick them 
out during an update) and the fact that `LVM2_LVM_TOOLS` also has a 
`default y`.

But I don't mind dropping this, if it's preferred to avoid accidentially 
pulling bash as dependency on an update.
