linux - rpmbuild does not preserve permissions of directories -

i have application in /opt/myapp need pack rpm package using fpm follows:

fpm -e -s dir -t rpm --name 'myapp' --version '1.0' --iteration "12345" --directories /opt/myapp --epoch 0 /opt/myapp 

(other options not relevant here)

all files , directories in myapp owned root (both user , group). there directory called "help" different permissions like

drwxrwxrwx. 

i.e. users can write directory. when inspect spec file generated fpm, has

%defattr(-,root,root,-) 

and directories (%dir) , files listed, expect original permissions preserved in package. however, when inspect using

rpm -qlvp myapp.rpm 

the permission on "help" directory reset to:

drwxrwxr-x 

i.e. other users cannot write there anymore. first guess add option

--rpm-use-file-permissions 

but made things worse, because files in rpm owned user called fpm.

edited: i've achieved result using

--rpm-use-file-permissions --rpm-user root --rpm-group root 

but still doesn't feel elegant , flexible. in advance.

the comment %defattr, , absence of comments buildroot tree may indicate confusion. according rpm.org:

if particular attribute not need specified (usually because file installed attribute set properly), attribute may replaced dash

that is, if no explicit permission given in %defattr, permissions build-time %install when constructing rpm satisfactory. there no guarantee match (or compatible with) actual system on rpm later installed.
