Description Dusty Mabe 2020-08-04 03:18:54 UTC

Description of problem:

The 85-write-ifcfg.sh pre-pivot hook seems to be able to miss writing out a bond ifcfg file into /tmp/ifcfg/ if it's combined with a vlan.


If I use kernel args like:

```
rd.break=cleanup rd.neednet=1 vlan=bond0.251:bond0 ip=192.168.122.111::192.168.122.1:255.255.255.0:myhostname:bond0.251:none:192.168.122.1 bond=bond0:ens2,ens3:mode=active-backup,miimon=100
```

I see only a single file get created in `/tmp/ifcfg/`:

```
# ls /tmp/ifcfg/
ifcfg-bond0.251

# cat /tmp/ifcfg/ifcfg-bond0.251
# Generated by dracut initrd
NAME="bond0.251"
ONBOOT=yes
NETBOOT=yes
UUID="5235ffc0-ff86-4d90-9583-b4d560e5974b"
BOOTPROTO=none
IPADDR="192.168.122.111"
NETMASK="255.255.255.0"
GATEWAY="192.168.122.1"
TYPE=Vlan
DEVICE="bond0.251"
VLAN=yes
PHYSDEV="bond0"
```

I would expect more files to get created that represent the bond and the slave devices.


If I leave the vlan out of the picture then more files do get created appropriately. With kernel arguments:

```
rd.break=cleanup rd.neednet=1 ip=192.168.122.111::192.168.122.1:255.255.255.0:myhostname:bond0:none:192.168.122.1 bond=bond0:ens2,ens3:mode=active-backup,miimon=100
```

we get:

```
cleanup:/# tail /tmp/ifcfg/* 
==> /tmp/ifcfg/ifcfg-bond0 <==
ONBOOT=yes
NETBOOT=yes
UUID="42aed295-2d2a-4710-b028-e25eceaa523f"
BOOTPROTO=none
IPADDR="192.168.122.111"
NETMASK="255.255.255.0"
GATEWAY="192.168.122.1"
BONDING_OPTS="mode=active-backup miimon=100"
NAME="bond0"
TYPE=Bond

DEVICE="ens3"
```


Version-Release number of selected component (if applicable):

```
$ rpm -q dracut
dracut-049-70.git20200228.el8.x86_64
```


How reproducible: Always


Steps to Reproduce:
See description


Actual results:

Only ifcfg-bond0.251 in /tmp/ifcfg/


Expected results:

More files getting created that represent the bonds and subordinate devices.
