Please avoid negative PACKAGECONFIGs. Instead use:
PACKAGECONFIG[new-mount-api] =
"--enable-libmount-mountfd-support,--disable-libmount-mountfd-support"
and add "new-mount-api" to the default for PACKAGECONFIG.
Also, how long will the "new" in "new-mount-api" be valid, i.e., what
happens when the next mount API comes along? It might be better to match
the feature name to the configuration option, e.g.:
PACKAGECONFIG[libmount-mountfd-support] =
"--enable-libmount-mountfd-support,--disable-libmount-mountfd-support"
