>Description:
In pkgsrc Makefiles, it is usual to align the values with one or more Tab characters after the = sign. This also works in mk.conf but not in pkg_install.conf:

 28138      1 pkg_info NAMI  "/etc/pkg_install.conf"
 28138      1 pkg_info RET   open 3
 28138      1 pkg_info CALL  read(3,0x7afb0b81c780,0x4000)
 28138      1 pkg_info GIO   fd 3 read 26 bytes
       "PKG_DBDIR=      /usr/pkg/pkgdb\n"
 28138      1 pkg_info RET   read 26/0x1a
[...]
 28138      1 pkg_info CALL  open(0x7afb0b825040,0x600004,0xea014d11)
 28138      1 pkg_info NAMI  "  /usr/pkg/pkgdb"
 28138      1 pkg_info RET   open -1 errno 2 No such file or directory


>How-To-Repeat:
Put the following in /etc/pkg_install.conf:

PKG_DBDIR=      /usr/pkg/pkgdb

(with a Tab in the middle)

n/a
